This is my first time building up a 3D printer, and I am running into issues. I now have 8 Benchie3D’s that all have tilt, to the same degree and I cant seem to find the root cause.
I have tried:
- Rotating the effector
- Changing around my endstops to try and make things worse/better
- Adjusting my arm_radius (was 178.54, now is 183.5)
- Tightening the belts
- Running a full tune
- Running with no tuning (remove config-override delta.grid, then resting)
- Printing through OctoPrint, Printing local SD card (print foo.gcode)
- Making sure my machine is square
My controller is a bit different than most. I am running an SDK V1.3 board with uStepperS drivers in a closed loop configuration.
I am honestly kinda stumped. I cant seem to find anything that effects the tilt, for better or worse. Any ideas???
More info that I hope can help:
(My calibration sequence)
G32 G28 (Full calibration, then return to home)
(Manually: jog down to touch the plate)
M306 Z0 (Set Z to 0)
G28 (Go home)
M500 (Save it)
reset
G31 (Full bed leveling)
M374 (Save bed leveling)
